Calorimetric flow meter for liquids and gases

New benchmark in thermal flow measurement

  • Optimised for water, oils, glycol and air
  • Fast response time and integrated temperature measurement
  • Red/green colour change for process values
  • Internal pipe diameter selectable from 15...400 mm
  • The process connection can be rotated for optimum alignment

Measurement technique
The SA volumetric flow sensor operates using the calorimetric measuring principle. Two measuring elements as well as a heat source are located on the measuring tip. The physical effect that a flowing medium absorbs heat energy and conducts it away is used. The resulting temperature change is an indication of flow.

Device function
The new SA-type sensor has been designed to detect and measure flow and temperature even in large internal pipe diameters up to 400 mm. Therefore it serves different applications. Switching outputs, analogue signals and IO-Link provide various options to further process the signals. That means that the user is best-equipped for Industry 4.0.
